Don't bother looking for them.  I thought you had generated them with some arcane app you had in your quiver.

I down loaded your file and I'm rendering now using a different glass and a copperish image based metal I made and turned down reflectivity on your metal.  I'll post when it finishes.  Then I'll ask a question about how to get a machines surface look.  A picture is worth a thousand words.  I'll post tomorrow.  It is after midnight here.  Bryce keeps me up too late.
